Doing sit-ups is simple and effective to practice abdominal muscles. You can also lie flat on the bed and touch your toes with both hands (lift your body). Do it slowly. If it is fast, there will be inertia, which will affect the effect. Be sure to do it to the end and do it in place.

Doing push-ups or using dumbbells (be sure to be heavy, or use barbells) to enter bench presses is the best way to practice pectoralis major.

It is advisable to have muscle aches every time. Remember not to do it every day. Every time you do anaerobic exercise, you should destroy your muscle tissue as much as possible, and then use enough time and nutrition to repair the damaged muscle tissue and let it grow. To put it bluntly, muscles grow out at rest after anaerobic exercise.

Must also be combined with aerobic exercise, such as jogging, be sure to sweat. If you simply do sit-ups, the fat layer will not decrease, the muscle layer will thicken and the waist will be thicker.
